ABSTRACT

Compositions for oxidation dyeing keratinous fibers, for example, human keratinous fibers such as hair, comprising, in a medium suitable for dyeing, at least one oxidation dye precursor chosen from 1-(4-aminophenyl)-pyrrolidines and acid addition salts thereof, and at least one cationic polymer. Dyeing methods and devices using said compositions.

[0001] The present invention relates to compositions for oxidation dyeing keratinous fibers, for example, human keratinous fibers such as hair, comprising, in a medium suitable for dyeing, at least one oxidation dye precursor chosen from 1-(4-aminophenyl)-pyrrolidines and acid addition salts thereof, and at least one cationic polymer.

[0002] It is known to dye keratinous fibers, for example, human hair, with dyeing compositions comprising oxidation dye precursors, generally called “oxidation bases.” Representative oxidation bases include ortho- and para-phenylenediamines, ortho- and para-aminophenols, and heterocyclic bases.

[0003] Oxidation dye precursors are compounds initially only slightly colored or not colored that develop their dyeing power in the hair in the presence of oxidizing agents, leading to the formation of colored compounds. The formation of these colored compounds results either from oxidative condensation of the “oxidation bases” with themselves, or oxidative condensation of the “oxidation bases” with color-modifying compounds, or “couplers,” which are generally present in the dyeing compositions used in oxidation dyeing. Representative couplers include meta-phenylenediamines, meta-aminophenols, meta-diphenols, and certain heterocyclic compounds.

[0004] The variety of compositions that can be employed in oxidation coloration, chosen from oxidation bases, oxidation couplers and mixtures of oxidation bases and couplers, can contribute to a palette very rich in color.

[0005] It is desirable for such oxidation dyes, otherwise called “permanent” dyes, to satisfy at least one of the following—make it possible to obtain shades of the desired intensity and tend to exhibit good resistance toward at least one external agent, such as, for example, light, adverse weather conditions, washing, permanent waving, perspiration, and rubbing.

[0006] Further, it is desirable that such dyes be able to cover grey hair, and thus should be the least selective possible, that is to say they should make it possible to obtain the smallest possible differences in color all along the same keratinous fiber, which may indeed be differently sensitized (i.e. damaged) between its tip and its root.

[0007] The permanent dyeing of hair with para-phenylenediamine (PPD) coupling products in the presence of hydrogen peroxide has been known for a long time and is in very widespread use. Nevertheless, better-tolerated oxidation bases have been sought and proposed as alternatives to PPD. For example, the tertiary base N,N-bis(β-hydroxyethyl)-para-phenylenediamine has been widely used in commercial hair-dyeing products, however, the colors obtained using these compositions tend to have at least one of the following drawbacks: less intense colors, less chromatic shades, or less resistant to various external agents to which the hair may be subjected.

[0008] The inventors have discovered that it is possible to overcome at least one of the above-mentioned drawbacks. By combining at least one (as used herein, “at least one” means one or more and thus includes mixtures and combinations) oxidation base chosen from 1-(4-aminophenyl)pyrrolidines and acid addition salts thereof with at least one cationic polymer, however, the inventors have just now discovered that it is possible to obtain oxidation dyes capable of producing shades of colors that may have at least one of the following properties: shades that are varied, chromatic, intense, aesthetic, not very selective, and/or that exhibit good resistance to the various attacks to which the fibers may be subjected.

[0009] As used herein, the term “lower alkyl” means an alkyl chosen from saturated and unsaturated, branched and unbranched C₁-C₆ alkyl groups.
